RISSimulation of the Madden–Julian Oscillation in a Coupled General Circulation Model. Part I: Comparison with Observations and an Atmosphere-Only GCM
Publisher: American Meteorological Society
Abstract: The simulation of the Madden?Julian oscillation (MJO) has become something of a benchmark test for the performance of GCMs in the Tropics over recent years. Many atmospheric GCMs have been shown to reproduce some aspects ...
Simulation of the Madden–Julian Oscillation in a Coupled General Circulation Model. Part II: The Role of the Basic State
Publisher: American Meteorological Society
Abstract: In Part I of this study it was shown that air?sea coupling had a positive impact on some aspects of the simulation of the Madden?Julian oscillation (MJO) by a GCM. However, errors in the basic-state climate of that GCM ...
The Importance of High-Frequency Sea Surface Temperature Variability to the Intraseasonal Oscillation of Indian Monsoon Rainfall
Publisher: American Meteorological Society
Abstract: While the Indian monsoon exhibits substantial variability on interannual time scales, its intraseasonal variability (ISV) is of greater magnitude and hence of critical importance for monsoon predictability. This ISV comprises ...
The Intraseasonal Variability of the Indian Summer Monsoon Using TMI Sea Surface Temperatures and ECMWF Reanalysis
Publisher: American Meteorological Society
Abstract: The northward-propagating intraseasonal (30?40 day) oscillation (NPISO) between active and break monsoon phases exerts a critical control on summer-season rainfall totals over India. Advances in diagnosing these events and ...
